You have been subscribed to a public bug:

Recently upgraded my Dell 1720 Laptop from Ubuntu 12.04 to 14.04

Results:  Flaky wifi disconnects after being on standby and will not
reconnect.

Eventually after several reboots it connects or suggested command on the
internet on how to resolve this.

The card is a BCM4321 wireless card.   
I have been through every article and forum post looking for an answer.   

I cannot connect to my work's public wifi.  Can connect at home but only
in certain curcumstances like if the plugs in.

Tried various scripts to kick it into life after resume.  Tried re-
installing drivers.  NOTHING.

Please can someone suggest what this could be and is there an actual
answerable fix?

Tried all these:

To no avail.   Any more answers on this greatly appreciated.
